Description
Technical field
The present invention relates to technical field of environment pollution control, in particular to a kind of compound moisturizing dust suppressant and preparation side
Method.
Background technique
Outdoor metal mine road vehicle is more, as the car passed by, it is easy to cause dust on the roads.Dust on the roads belongs to out
Putting property fugitive dust, dispersion are difficult to settle in air, not only cause the damage of mechanical equipment, enterprise is made to suffer economic loss, and
Also air can be polluted, the most serious is being detrimental to health, being exposed under the higher environment of dust concentration for a long time makes one to suffer from dirt
The probability of tuberculosis increases, and pneumoconiosis proportion in occupational disease is high.The technology of dust at present control has many sides
Method mainly has watering dust suppression, air partition dust suppression, covering method dust suppression and chemical dust suppression.
Dust on the roads belongs to open dust, is one of main dirt source in mine, the watering dust prevention dust suppression time is short and wastes
Water resource.Although air partition dust suppression effect is good, there is not yet the influence of season problem, the duration is long, is not suitable for road
Dust suppression.Covering method is dust-proof suitable for material heap, will use a large amount of manpower and material resources when on road, not can effectively solve and ask
Topic, and after tarpaulin self-corrosion pollution can be again resulted in overcover and environment.Chemical dust suppression has road dust suppression
Apparent anti-dust effect, and controllable costs, receive and are widely applied.
Summary of the invention
An object of the present invention is exactly to have overcome the deficiencies of the prior art and provide a kind of compound moisturizing dust suppressant and system
Preparation Method, it is low in cost, facilitate that production, corrosivity are small, anti-dust effect is good, meet environmental requirement.
The present invention adopts the following technical scheme:
A kind of compound moisturizing dust suppressant includes Sodium Polyacrylate 0.075~0.085%, sodium metasilicate by mass percentage
10~20%, polyethylene glycol 1.7~2.3%, alkyl glycosides 0.1~0.2%, surplus are water.
It further, by mass percentage include Sodium Polyacrylate 0.08~0.083%, sodium metasilicate 15~18%, poly- second
Glycol 1.8~2%, alkyl glycosides 0.15~0.18%, surplus are water.
It further, by mass percentage include Sodium Polyacrylate 0.08%, sodium metasilicate 15%, polyethylene glycol 1.9%, alkane
Base glucosides 0.15%, surplus are water.
Further, by mass percentage include Sodium Polyacrylate 0.082%, sodium metasilicate 17%, polyethylene glycol 1.9%,
Alkyl glycosides 0.16%, surplus are water.
The present invention also provides a kind of preparation methods of compound moisturizing dust suppressant, first will be in 10~20% sodium metasilicate water
Be uniformly mixed, then by mass percentage be added 0.075~0.085% Sodium Polyacrylate, 1.7~2.3% polyethylene glycol and
0.1~0.2% alkyl glycosides is slowly stirred uniformly, obtains compound moisturizing dust suppressant stoste.
The principle that each component of the present invention is selected is as follows:
1, Sodium Polyacrylate and sodium metasilicate are selected simultaneously.Sodium Polyacrylate is as a kind of sodium salt coalescence agent, in very little concentration
Under apparent consolidation can be played to dust so that solution reaches larger viscosity；It is a kind of that sodium metasilicate, which is equally used as sodium salt,
Hygroscopic agent, it was proved that needing just to can achieve excellent hygroscopic effect under larger concentration.Applicant sends out in practice
Existing: sodium polyacrylate solution has biggish viscosity, and a large amount of sodium metasilicate powder not readily dissolves in the biggish solution of viscosity, first
Sodium metasilicate powder, which is added, can accelerate solution rate, dissolve it preferably, the dust suppression agent solution of preparation does not precipitate uniformly.Together
When, rationally determine that the concentration of Sodium Polyacrylate and sodium metasilicate is also extremely important, by largely testing, Sodium Polyacrylate 0.075
~0.085%, good result can be reached when sodium metasilicate 10~20%.
2, alkyl glycosides dissolubility is good, resistance to highly basic and electrolyte, good with skin intermiscibility, nontoxic, non-stimulated, easy biology drop
Solution.It can make the storage of long period within the scope of larger temperature, meanwhile, have the function of humidification, is a kind of " live on green surface
Property agent ".And other surfaces activating agent it is poor there are resistance to hard water and to skin have certain irritation, it is insensitive to hard water, with
The raising of water temperature, solubility can gradually decrease, slowly some oxidation products of oxidation generation are big to dermal toxicity in air for meeting
The disadvantages of.
The invention has the benefit that have the characteristics that nontoxic, non-corrosive, at low cost, preparation process is simple, safety,
The dust being dispersed in upper pavement surface air can be removed.And when being sprayed at surface of material, dust can be made with certain intensity
It is bonded together non-breakable, and the moisture in air can be absorbed, dust is made to keep certain water capacity, to have dust-proof
Depositing dust effect.
Detailed description of the invention
Fig. 1 show the effect contrast figure of sprinkling dust consolidation；(a) spray agent is water；(b) spray agent is that the present invention is implemented
The compound moisturizing dust suppressant of example.
